Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the inter
Igoryamba

Answer:

Average\ Rate = 48

Step-by-step explanation:

Given

See attachment for table

Required

Determine the average rate of change over 5\le x \le 7

Average rate of change is calculated using:

Average\ Rate = \frac{f(b) - f(a)}{b - a}

Where

a \le x\le b

In this case:

a = 5;\ \ \ b = 7

Average\ Rate = \frac{f(b) - f(a)}{b - a}

Average\ Rate = \frac{f(7) - f(5)}{7 - 5}

Average\ Rate = \frac{f(7) - f(5)}{2}

From the table:

f(7) = 108

f(5) = 12

The expression becomes

Average\ Rate = \frac{108 - 12}{2}

Average\ Rate = \frac{96}{2}

Average\ Rate = 48
